ABSTRACT The use of a thermoelectric generator (TEG) in generating useful power from solar thermal energy is demonstrated. This device represents a portable and autonomous power generation system operating from solar power, capable of powering micro/nano systems. The TEG was integrated with a micro solar thermal collector plate to enhance the thermal radiation absorption capacity of the hot sid...
Changes in arterial wall composition and function underlie all forms of vascular disease. The fundamental structural and functional unit of the aortic wall is the medial lamellar unit (MLU). While the basic composition and organization of the MLU is known, three-dimensional (3D) microstructural details are tenuous, due (in part) to lack of three-dimensional data at micro- and nano-scales. We ap...
Tuning the self-assembly of building blocks to obtain a kaleidoscope of nanostructures is very important and challenging for the preparation of advanced nanomaterials. Amphiphiles confined within carbon nanotube (CNT) arrays can self-assemble into complex structures that maintain the "bilayer" characteristic of a lamellar phase, we call them "lamellar phase variants (LPVs)". In this work, we ca...
A liquid cooling plate structure with multiple channels is proposed for linear synchronous motor in this paper. Firstly, a conjugate heat dissipation model established, and coupling analysis fluid temperature fields performed by finite volume method different channel numbers section shapes. The simulation results show that, the capacity of observably improved, especially 6-channels elliptical s...
هدف: تحقیقات بر روی tilt board که اختصاصاً جهت تمرینات تعادلی طراحی گشته بسیار محدود است. هدف ما در این مطالعه بررسی اثر تمرین با tilt board بر مولفه های استاتیک و دینامیک تعادل بعد سکته بود. روش: در این مطالعه ?? بیمار همی پلژی شرکت داشتند که بطور تصادفی به دو گروه مداخله و کنترل دسته بندی شدند. بیماران با استفاده از آزمون های کلینیکی، دستگاه force plate و biodex قبل و بعد درمان مورد ارزیابی ...
different languages are classified in different types according to different elliptical positions in coordinate sentences. in the following, i shall briefly outline this typology and then show the status of persian in this hierarchy. moreover, i will demonstrate that two functional factors; ease of processing and temporal order, are in competition to specify the elliptical positions in these se...
